Close Resemblance

The radical cations of tetracene, chrysene, 1,2-benzanthracene, and 3,4-benzphenanthrene have been produced in boric acid glass by u.v. irradiation. Their electronic spectra are recorded in the region 200–1400 nm and show a close resemblance to the available data for the cations reported earlier.

Localized Orbital

Two models are used to analyze the spectra of aniline and nitrobenzene. These are the localized-orbital model, in which there is no delocalization of the electrons between the phenyl group and the substituent, and the iso-conjugate-hydrocarbon model, in which there is complete delocalization. Neither model is very satisfactory with zero-order wave functions and energies. Both give a satisfactory interpretation of the spectra if configuration interaction is taken into account but the localized-orbital model is rather better for calculating energies. The localized-orbital model is also more readily applied to polysubstituted benzenes.
